BACKGROUND OF THE INVENTION
The present invention relates to an object display device and a program for displaying a plurality of objects in a drawing area on a display screen at a location indicated by the display position information.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a data processing apparatus equipped with drawing software or the like, when various objects created are drawn on a display screen, various kinds of objects can be applied to a desired object by a button operation or a mouse operation on the screen. I was doing the operation. For example, when a plurality of objects are displayed in a layered manner, the plurality of objects are managed as layers, so that each object can be operated for each layer.
In this case, it is also known that an object attribute can be easily set for each layer. For example, if you select an arbitrary graphic element for graphic data with multiple graphic elements superimposed and set its display attributes, the graphic display method will change the graphic data based on this setting and display it. Is known (Patent Document 1).

[Problems to be solved by the invention]
However, in the above-described prior art, the graphic element to be set is selected when setting the display attribute. For example, when the number of layers is large or a large number of graphic data is displayed on the same screen. If it is displayed, it is difficult to select a setting target, and there is a possibility that an incorrect setting is made.
By the way, in layer management in drawing software, the following problems generally occur. In FIG. 17, a plurality of objects a, b, and c are displayed in a layered manner and a plurality of objects d, e, and f are displayed in a layered manner in a drawing area on the display screen. It is the figure which showed the state. Here, the hierarchical order of each object is the order of “c, b, a” and the order of “f, d, e” from the front (front) to the back (back). In this case, the object e is obscured by the objects d and f above it and cannot be actually seen. Therefore, the presence of the object e may be missed. For example, if an operation of moving the objects d and f that are higher than the object e is performed, the object e also moves together with the operation. Also, the operation of moving back one by one from the top layer to confirm the existence of the object e becomes more troublesome as the number of layers increases. Furthermore, it is not easy to check which objects are in the same hierarchy, and there is a risk of mistakes.
[0005]
An object of the present invention is to provide an auxiliary area separately from a normal object drawing area on a display screen so that information relating to a group classified according to the attribute of an object can be easily confirmed by display contents of the auxiliary area. It is.

[0033]
FIG. 9 is a block diagram showing basic components of the object display device in this embodiment.
The CPU 101 is a central processing unit that controls the overall operation of the object display device in accordance with the operating system and various application software in the storage device 102.

The recording device 102 may be configured to be able to mount a removable storage medium such as a CD-ROM or DVD in addition to a fixed memory such as a hard disk. The programs and data in the storage device 12 are loaded into a RAM (for example, static RAM) 103 as needed, or the data in the RAM 103 is saved in the storage device 102. The RAM 103 has a program execution area and a work area.
[0034]
Further, the CPU 101 can directly access and use programs / data on the other electronic device side via the communication device 104, or can receive and download via the communication device 104. The communication device 104 is, for example, a wired / wireless communication interface including a communication modem, an infrared module, an antenna, and the like. On the other hand, an input device 105 and a display device 106, which are input / output peripheral devices, are connected to the CPU 101 via bus lines, and the CPU 101 controls their operations in accordance with the input / output program. The input device 105 is an operation unit that constitutes a pointing device such as a keyboard, a touch panel, a mouse, or a touch input pen, and inputs character string data and various commands. The display device 106 is a liquid crystal display device that performs full-color display, a CRT display device, a plasma display device, or the like.
[0035]
Next, the operation concept of the object display device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. It is also possible to sequentially execute operations according to the program code transmitted via the transmission medium. That is, in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium.
[0036]
FIG. 10 is a flowchart showing the operation when the auxiliary area information 15 is set.
First, when instructed to execute the setting process of the auxiliary area information 15, the CPU 101 adds a new area for setting new auxiliary area information (step A1). In this state, when an “adjacent direction” indicating which part of the drawing area 2 is adjacent to the auxiliary area 3 is input, the input “adjacent direction” is set in the corresponding item in the new area. (Step A1). Hereinafter, “horizontal dot size” and “vertical dot size” input setting processing (step A3), “maximum number of groups” input setting processing (step A4), and “group rank determination attribute information” indicating the entire area size are shown. ”Input setting process (step A5) and“ simple graphic display color determining attribute information ”input setting process (step A6) are sequentially executed.
[0037]
When the setting of one auxiliary area information 15 is completed in this way, it is checked whether or not the setting end is instructed (step A7), and the process returns to the first step A1 until the end instruction is given. The setting process for the auxiliary area 3 is repeated. The auxiliary area information 15 can be set to a maximum of four types. When the auxiliary area 3 is adjacent to the four sides of the drawing area 2 one by one, the four types of auxiliary area information 15 may be set. The “horizontal dot size” and “vertical dot size” may be fixed sizes, and the “maximum number of groups” is automatically detected and set according to the addition or deletion of objects. You may make it do.
[0038]
When the object display is instructed in the state where the auxiliary area information 15 is set as described above, the drawing area 2 is displayed on the display screen 1 and the auxiliary area 3 is referred to by referring to the auxiliary area information 15. A display is output adjacent to the drawing area 2. That is, after determining the arrangement position based on the “adjacent direction” read from the auxiliary area information 15, the CPU 101 determines the overall size based on the “horizontal dot size” and the “vertical dot size” and assists it. Area 3 is arranged and displayed. Then, the group rank management table 13 is accessed based on the “group rank determining attribute information” read from the auxiliary area information 15, the group rank is determined according to the definition contents, and the “maximum” read from the auxiliary area information 15 is read. The number of groups corresponding to the “number of groups” is allocated in the auxiliary area 3 according to the order of determination. In this case, group handles corresponding to the “maximum number of groups” are arranged and displayed outside the auxiliary area 3 in the auxiliary area 3 as shown in FIG.
[0039]
FIG. 11 and FIG. 12 are flowcharts showing the overall processing at the time of object display, and the execution is started in response to an interruption by a key or mouse operation. Here, when the drawing area 2 and the auxiliary area 3 are displayed on the display screen 1, when the CPU 101 detects an interrupt operation by a key or mouse operation, the operated area is the drawing area 2 or the auxiliary area 3. However, if the drawing area 2 is operated, the process proceeds to step B2 to check the contents of the instruction. If the object is generated, that is, from the drawing menu 4 in the drawing area 2. When “Generate” is selected, execution of processing for additionally creating new object management information 11 is started (step B3).
[0040]
For example, if the object type is a figure type, a figure corresponding to the type is displayed at a designated position on the drawing area 2. When a size change operation is performed in this state, enlargement / reduction processing is performed to obtain “X direction dot size” and “Y direction dot size”, and when input confirmation is instructed, the generated new object is related to Various types of information, that is, “type information”, “X direction dot size”, “Y direction dot size”, “color information”, “drawing data”, “display position information”, “layer”, “display state (initial state) "Value: display)" is set in the corresponding item in the object management information 11, and "simple graphic identification information" is generated and additionally set.
When a new object is generated in this way, the process proceeds to the next step B4 to start processing for generating the corresponding simple graphic management information 12.
[0041]
FIG. 13 is a flowchart showing a process for generating the simple graphic management information 12.
FIG. 13 shows the case where the simple graphic management information is generated for the auxiliary area 3 adjacent to the lower part of the drawing area 2 and the simple graphic management information for the auxiliary area 3 adjacent to the left part of the drawing area 2. In the figure, among the “vertical (horizontal) direction” or “horizontal (vertical) direction” described in each step, the description outside the parentheses is as follows: The auxiliary area 3 adjacent to the lower part and the description in parentheses are for the auxiliary area 3 adjacent to the left part.
[0042]
First, the CPU 101 accesses the object management information 11, reads the “X direction dot size” or “Y direction dot size” of the new object generated this time, and sets the horizontal (or vertical) dot size of the simple figure. The same value as the “X direction dot size” or “Y direction dot size” of the object is set (step C1). That is, in the case of the auxiliary area 3 adjacent to the lower part of the drawing area 2, a value obtained by matching the horizontal dot size of the simple figure to the “X direction dot size” of the object, or the left end of the drawing area 2 In the case of the adjacent auxiliary area 3, a value obtained by matching the vertical dot size of the simple graphic with the “Y-direction dot size” of the object is set in the corresponding item of the simple graphic management information 12.
[0043]
Next, the dot size in the vertical direction (or horizontal direction) of the simple figure is calculated according to the calculation formula of INT (YD / MG / 2) or INT (XD / MG / 2) (step C2). That is, in the case of the auxiliary region 3 adjacent to the lower part of the drawing region 2, the “vertical dot size (YD)” and the “maximum number of groups (MG)” are read from the auxiliary region information 15 and this “vertical dot size” is read out. (YD) "is divided by" maximum number of groups (MG) "to calculate the vertical size per group, and this 1/2 size is calculated as the vertical size of the simple figure. The remaining ½ size is a blank space (between lines) between simple figures in the vertical direction. “INT” indicates an integer function (hereinafter the same).
[0044]
Similarly, in the case of the auxiliary area 3 adjacent to the left end portion of the drawing area 2, “horizontal dot size (XD)” and “maximum number of groups (MG)” are read from the auxiliary area information 15, and this “horizontal direction” is read out. The horizontal size per group is calculated by dividing the “dot size (XD)” by the “maximum number of groups (MG)”, and this ½ size is calculated as the horizontal size of the simple figure. The dot size in the vertical direction (or horizontal direction) of the simple graphic calculated in this way is set in the corresponding item of the simple graphic management information 12.
[0045]
Then, the process proceeds to the next step C3, where it is checked whether or not “simplified graphic display color determining attribute information” is set in the auxiliary area information 15 currently focused on. The process for determining the display color is started, but if there is no setting, the display color determination process is skipped. If “simple graphic display color determination attribute information” is set, “simple graphic display color determination attribute information” is read from the auxiliary area information 15 and the object attribute is read from the object management information 11. The simple graphic display color management table 14 is accessed to determine the display color corresponding to the object attribute. For example, if “attribute information for determining simple graphic display color” is “type” and the object attribute is “rectangular”, “green” is determined as the display color of the simple graphic corresponding to this object. The display color determined in this way is set in the corresponding item of the simple graphic management information 12.
[0046]
Furthermore, “rectangle” is set as “type information” in the simple graphic management information 12, and “type information”, “X direction dot size”, “Y direction dot size”, and “color information” are "Drawing data (rectangular data)" is created and set (step C4). Then, as the display position information for arranging the rectangular data in the auxiliary area 3, the position coordinate in the horizontal (vertical) direction is set to the same value as the position coordinate in the horizontal (vertical) direction as the display position information of the object. Set (step C5). That is, in the case of the auxiliary area 3 adjacent to the lower part of the drawing area 2, a value obtained by matching the horizontal position coordinate of the simple figure with the “X coordinate” of the object, or adjacent to the left end of the drawing area 2. In the case of the auxiliary area 3, a value obtained by matching the vertical position coordinate of the simple graphic with the “Y coordinate” of the object is set in the corresponding item of the simple graphic management information 12.
[0047]
Next, “group order determination attribute information” is read from the auxiliary area information 15, the object attribute is read from the object management information 11, the group order management table 13 is accessed, and the group order (Z) corresponding to this object attribute is accessed. Is specified (step C6). For example, if the “group order determination attribute information” is “layer” and the object attribute is “1”, “1” is specified as the group order (Z) corresponding to this object. If the “group order determination attribute information” is “type” and the object attribute is “circle”, “2” is specified as the group order (Z) corresponding to this object.
[0048]
Next, the vertical (or horizontal) position coordinates of the simple figure are calculated according to the calculation formula of INT (YD / MG /) * Z or INT (XD / MG) * Z (step C7). That is, in the case of the auxiliary region 3 adjacent to the lower part of the drawing region 2, the “vertical dot size (YD)” and the “maximum number of groups (MG)” are read from the auxiliary region information 15 and this “vertical dot size” is read out. (YD) "is divided by" maximum number of groups (MG) "to calculate the vertical size per group, and by multiplying this calculated size by the group order (Z), the vertical position coordinates are calculated. calculate.
[0049]
Similarly, in the case of the auxiliary area 3 adjacent to the left end portion of the drawing area 2, “horizontal dot size (XD)” and “maximum number of groups (MG)” are read from the auxiliary area information 15, and this “horizontal direction” is read out. The horizontal size per group is calculated by dividing the “dot size (XD)” by the “maximum number of groups (MG)”, and the horizontal size is calculated by multiplying the calculated size by the group order (Z). Calculate the coordinates. The position coordinates of the simple figure calculated in this way in the vertical direction (or horizontal direction) are set in the corresponding item of the simple figure management information 12.
[0050]
When the process of generating the simple graphic management information 12 is completed in this way, the process proceeds to step B5 in FIG. 11, and each object is arranged in the drawing area 2 based on the object management information 11 and displayed in a superimposed manner. That is, referring to “display management information” in the simple graphic management information 12, each “drawing data” other than “non-display” is sequentially read from the lowest layer indicated by “layer”, and the “display position information” is used as the “display position information”. Arrange sequentially at the indicated position coordinates.
Next, the simple graphic management information 12 is accessed with reference to the “simple graphic identification information” in the simple graphic management information 12, and each simple graphic is sequentially allocated and displayed in the auxiliary area 3 (step B6). That is, each “drawing data (rectangular data)” is read from the simple graphic management information 12 and sequentially arranged at the position coordinates indicated by the “display position information”.
[0051]
Thereafter, the above-described operation is repeated each time a new object is generated. Here, when “edit” is selected from the drawing menu 4 in the drawing area 2 in order to edit the object in the drawing area 2, this is detected in step B2, and the process proceeds to step B7. Select a new object to be edited from within, select additional objects, or narrow down the selection. For example, in the state where the objects a, b, and c and the objects d, e, and f are displayed in the drawing area 2 as shown in FIG. When specified, these objects a, b, and c are collectively specified as editing targets, or when only one object a is clicked, only the object a is specified. At this time, if a plurality of objects belonging to layer 2 and layer 3 have already been selected for editing, for example, by a process described later, the range including the objects a, b, and c is specified by additional selection. In this case, the objects a and c are newly added to the editing target, and if the area including the objects a, b, and c is specified by further narrowing down, the objects a, b, and c are selected. Only the object b, which is an object belonging to the layer 2 or layer 3, is the final editing target. The object to be selected is specified by changing the finally selected object or objects to the selected state simultaneously.
[0052]
Then, the contents of the drawing menu 4 in the drawing area 2 are switched to the editing menu, and when any editing content is instructed from the editing menu, for example, object deformation, display position change, layer position change, coloring change Etc. is instructed, the object to be edited is changed in accordance with the contents of the instruction (step B8). Then, the process moves to a process of changing a simple figure based on the edited content (step B9). In this case, basically the same process as the above-described step B4 (process of FIG. 13) is performed. Thereafter, the process proceeds to object display processing (step B5) and simple graphic display processing (step B6).

On the other hand, when an operation is performed on the auxiliary area 3 (step B1), it is determined whether the operation portion is a simple figure or a group handle (step B10 in FIG. 12). Here, if it is a simple figure, it is determined whether the operation content is movement or selection (step B11). If a simple figure move operation is performed, it is checked whether the move direction is the group rank direction or the coordinate axis direction parallel to the drawing area 2. If the move operation is in the group rank direction, the move destination is checked. A process of changing the object attribute based on the group is performed (step B12). For example, when the layer is changed, the “layer” of the object is changed to the “layer” associated with the destination group. A process of changing the display position information (coordinate values corresponding to the group rank direction) of the simple graphic in accordance with the change of the object attribute is also performed.
[0054]
If it is a movement operation in the direction of the coordinate axis parallel to the drawing area 2, a process of changing the display position information of the corresponding object is performed along with this movement (step B13). That is, when the simple figure in the auxiliary area 3 adjacent to the lower part of the drawing area 2 is moved in the X-axis direction, the X coordinate of the object is slid in the same direction by the amount of movement, and the drawing area When the simple figure in the auxiliary area 3 adjacent to the left part of 2 is moved in the Y-axis direction, the Y coordinate of the object is slid in the same direction by the amount of movement.
Note that processing for changing the display position information (coordinate values in the direction of the coordinate axis parallel to the drawing area 2) of the simple graphic in accordance with the change in the display position of the object is also performed. When the movement in the coordinate axis direction parallel to the drawing area 2 is performed simultaneously with the movement in the group order direction, the display position information is changed together with the change in the object attribute (steps B12 and B13). .
[0055]
When the simple graphic is moved in the auxiliary area 3 as described above, the object display process (step B5) and the simple graphic display process are executed to link the corresponding object with the simple graphic. (Step B6).
FIG. 14 exemplifies the case where the simple figure of the object e is moved from the position of the group handle “4” to the position of “1” by the drag operation of the mouse. The layer of the object e is changed according to the movement of the simple figure. Is changed from “4” to “1”, so that the object e is displayed in front of the drawing area 2 as shown in the figure. The destination group handle is highlighted as shown in the figure.
[0056]
When an operation for selecting one or more arbitrary simple figures in the auxiliary area 3 by a mouse click or the like is performed (step B11), the corresponding object is changed to a selected state in conjunction with this. The selection target is clearly indicated (step B14). For example, the object is clearly indicated by blinking or highlighting the object. In addition, in a state where a plurality of objects are already selected at the same time, when additional selection or further selection narrowing is performed, the same selection processing as that in step B7 described above is performed. The object to be selected is specified by changing the finally selected object or objects to the selected state simultaneously. By specifying the selection target in this way, it is possible to confirm the existence of the object, and to instruct editing, display / non-display, layer change, etc. of the selected object.
[0057]
If the operation part to the auxiliary area 3 is a group handle (step B10), it is determined whether the operation content is “move”, “select”, or “current group order designation” (step B15). Assuming that the operation of moving the group handle is performed, each simple figure belonging to one or more groups designated for movement is moved in groups, and all object attributes corresponding to each simple figure are displayed. The change is made based on the destination group (step B16). Even in the case of such movement in units of groups, processing for changing the display position information (coordinate values in the group order direction) of simple figures in accordance with the change of the object attribute is also performed. Thereafter, an object display process (step B5) and a simple graphic display process are executed (step B6).
[0058]
FIG. 15 is a diagram showing a display example when the group handle “4” is moved between “1” and “2” by dragging and dropping with the mouse. In this case, the objects a and e which were the layer “4” before the movement become the layer “2” after the movement, and the objects b and f which were the layer “2” before the movement are the layer “3” after the movement. Furthermore, the object d which was the layer “3” before the movement becomes the layer “1” after the movement.
[0059]
When an operation for selecting one or a plurality of arbitrary group handles is performed (step B15), all objects corresponding to each simple figure belonging to the selected group are collectively changed to a selected state and selected. The object is specified (step B17). In addition, in a state where a plurality of objects are already selected at the same time, when additional selection or further selection narrowing is performed, the same selection processing as that in step B7 described above is performed.
[0060]
If an arbitrary group handle is designated as the current group order (step B15), the designated group position is temporarily stored in the auxiliary area information 15 as the current group order, and then higher than the current group order. All objects belonging to the group handle are changed to the non-display state (step B18). In this case, each target object in the object management information 11 is accessed, and the “display state” is changed from “display” to “non-display”. Thereafter, the process proceeds to the object display process (step B5) and the simple graphic display process (step B6).
FIG. 16 is a diagram showing a display example when the group handle “3” is designated as the current group order. In this case, all objects belonging to the group handles “2” and “1” above the position of the designated group handle “3” are changed to the non-display state.
[0061]
As described above, in the object display device of this embodiment, a plurality of group information obtained by classifying each object based on its attribute (for example, layer) is assigned to each object, and one coordinate axis in the plane coordinate system is assigned. In the state in which the auxiliary area 3 in which the group information is associated with the other coordinate axis and the display position information of the object is associated with the object drawing area 2 is displayed on the display screen 1 in correspondence with the objects in the drawing area 3. Since each generated simple figure is displayed at a position in the auxiliary area 3 specified by the group information and display position information of the object, which object in the drawing area corresponds to which simple figure in the auxiliary area. In addition to being able to immediately confirm the correspondence relationship, it is known only by looking at the contents of the drawing area. Even if it is information about group classification of objects that are difficult to understand (for example, layers), it can be easily confirmed just by looking at the contents of the auxiliary area, and the display in the auxiliary area is a simple figure (rectangle) In addition, since the entire auxiliary area can be made compact, the display screen is not unnecessarily occupied.
[0062]
In this case, each time a new object is generated, a corresponding simple figure is automatically generated, and each time an object is edited, the simple figure is automatically edited based on the edited content. And the operator does not need to be aware of the generation and editing of simple figures. The auxiliary area 3 is arranged adjacent to the drawing area 2 and a simple figure having the same size as the actual size of the object is present on the coordinate axis parallel to the X coordinate axis or the Y coordinate axis of the drawing area 2. Since it is displayed in association with the object, the correspondence relationship between which object in the drawing area 2 corresponds to which simple figure in the auxiliary area 3 is further clarified.
[0063]
Further, the group classified based on the first attribute (for example, layer) and the group classified based on the second attribute (for example, type) of the object can be identified in one auxiliary area 3. For this reason, since each simple figure belonging to the group classified based on the second attribute is color-coded by a specific color, different group classifications classified from two viewpoints are made in one auxiliary region 3. It becomes possible to confirm simultaneously and easily.
[0064]
Also, an auxiliary area 3 adjacent to the drawing area 2 in the vertical direction and an auxiliary area 3 adjacent to the drawing area 2 in the horizontal direction are provided, and simple graphics corresponding to each object are separately displayed in each auxiliary area 3. Thus, one object can be comprehensively confirmed by the auxiliary area 3 from two directions.
Further, as shown in FIG. 3, the auxiliary area 3 related to the group classified based on the first attribute (layer) of the object and the auxiliary area 3 related to the group classified based on the second attribute (type). By providing separately, two kinds of attributes (layer, type) of the object can be separately confirmed by the dedicated auxiliary area 3.
It should be noted that if the size per group is calculated by the calculation formula of INT (YD / MG / 2) or INT (XD / MG / 2), even if the number of groups is large, all the simple figures in the auxiliary area 3 Since each group is equally spaced, the display contents are orderly and the legibility is improved.
[0065]
On the other hand, when an input operation is performed on a simple graphic placed in the auxiliary area 3, processing related to the object corresponding to the operated simple graphic is executed. An input operation on a simple graphic can be handled in the same way as an operation performed on a corresponding object in the drawing area 2, and an instruction to execute processing is also given to an object that cannot be seen in the normal object drawing area. be able to. That is, when an arbitrary simple figure in the auxiliary area 3 is selected by a mouse click or the like, the corresponding object is selected in conjunction with it, so that the selected object is edited, displayed / hidden, layer changed, etc. Can be instructed.
[0066]
In addition, when the simple figure in the auxiliary area 3 is moved in the group order direction, the attribute of the object corresponding to the simple figure is changed based on the destination group. The group (attribute) of the corresponding object can be easily changed only by moving in the rank direction, and the group can be changed for each object. In this case, when the simple figure in the auxiliary area 3 is moved in the group order direction and this simple figure is moved in the coordinate axis direction corresponding to the display position information, the group change of the object and its display position are performed. These changes can be made simultaneously and quickly, and the operability can be improved. When an arbitrary simple graphic is selected in the auxiliary area 3, the object corresponding to the selected graphic is selected as a processing target, and the corresponding object is selected in conjunction with the selection operation of the simple graphic. be able to.
[0067]
Further, when the simple graphic in the auxiliary area 3 is operated for each group, the processes related to all objects corresponding to the simple graphic in the operation group can be executed collectively. That is, when a group handle movement operation is performed, each simple graphic belonging to one or more groups designated for movement is moved in groups, and all object attributes corresponding to each simple graphic are displayed. Since the change can be made based on the movement destination group, it is possible to move the objects collectively in groups.
In addition, when an operation to select an arbitrary group handle is performed, all the objects corresponding to each simple figure belonging to the selected group are set to the selected state. It can be carried out. Furthermore, when an arbitrary group handle is designated by the current group order, all objects belonging to a group handle higher than the designated group position can be hidden.
[0068]
In the above-described embodiment, the auxiliary area 3 related to the group classified based on the object attribute (layer) is arranged adjacent to the lower part of the drawing area 2, or classified based on another object attribute (type). Although the auxiliary area 3 related to the group is arranged adjacent to the left part of the drawing area 2, the arrangement position thereof is arbitrary. In this case, the “adjacent direction” of the auxiliary area information may be set arbitrarily.
[0069]
Further, a plurality of auxiliary regions 3 may be arranged adjacently in parallel at the lower part or the left part of the drawing region 2. That is, for example, two auxiliary areas 3 may be arranged in parallel along the vertical direction below the drawing area 2, and each auxiliary area 3 may be grouped according to different object attributes. In this case, a plurality of auxiliary area information may be set and the “adjacent direction” may be the same direction.
As shown in FIG. 3, when a plurality of auxiliary areas 3 are arranged adjacent to each other, the auxiliary areas 3 may be grouped according to the same object attribute. In this case, the “group order determination attribute information” in the plurality of auxiliary area information may be set to the same attribute.
[0070]
In the above-described embodiment, “layer”, “type”, and “object color” are exemplified as object attributes. However, as other attributes, for example, “creator”, “creating department”, “generation date” of the object Or “distribution destination”.
Furthermore, in the above-described embodiment, a composite object obtained by hierarchically combining a plurality of element objects has been illustrated. However, the object is not limited to a layer structure object, and may be a planar arrangement object. It may be an object.
[0071]
In the above-described embodiment, when an arbitrary group handle is designated as the current group order, all the objects belonging to the group handle higher than the designated group position are changed to the non-display state. All objects in the group handle lower than the current group designation position may be hidden.
Further, the object is not limited to various figures and characters, and may be image data such as an image, or may be a window (window-like display area).
[0072]
Further, when a plurality of simple figures in the same group completely overlap or most of the parts overlap in the auxiliary area 3, the respective display positions may be shifted by a predetermined amount until each simple figure can be identified. .
Further, when selecting an arbitrary simple figure in the auxiliary area 3, a range may be designated by operating a mouse or the like, and a plurality of simple figures existing in the designated range may be selected simultaneously.
[0073]
In the above-described embodiment, the object is specified by the display position and size in the object management information. However, the object may be specified by two-point coordinates (minimum coordinate and maximum coordinate).
In the embodiment described above, the simple graphic is “rectangular”, but the shape of the simple graphic is not limited to this, and may be, for example, an ellipse, a thick line, a broken line, a line with arrows at both ends, or the like. Any shape can be used as long as it is simple and easy to see. In this case, for example, a simple figure is a point-like figure, and a position of any one of the left end, center, and right end of the object is displayed in association with the point-like figure, so that a plurality of simple figures can be easily created in the same group. May not overlap.
[0074]
In addition, the object display device of the above-described embodiment is not limited to the stand-alone type, and each component is physically separated into two or more housings, a wired transmission path such as a communication line or a cable, a radio wave, You may comprise the distributed computer system which transmits / receives data via wireless transmission paths, such as a microwave and infrared rays.
[0075]
